sweetbrett Posted July 2, 2009 Share Posted July 2, 2009 I installed osx 10.5 a few months ago. it worked fine, i was able to update to 10.5.5 no problem. then i stopped using it for a while, and decided yesterday i wanted to try it out again (multiboot system with vista and ubuntu). Vista and Ubuntu boot fine, but osx will not boot in to the desktop. if i try the -x or -s or -xs boot opions, I see all the drivers loading, but it seems it gets to the end of loading them then decides to reboot. I can boot the install cd fine and reinstall fine, but i get the same problem when i try to boot in to a fresh 10.5.2 system. I tried to look for a boot log, /var/log/system.log, but its not there. Any ideas on how I might fix this? Link to comment https://www.insanelymac.com/forum/topic/173288-cant-boot-osx-anymore/ Share on other sites More sharing options...

engenius Posted July 7, 2009 Share Posted July 7, 2009 if you can get another hard drive and install OSX and OSX only! its becuz (Most likely) you do not hav your drive formated to a GPT table to fix this (This will wipe your drive fyi) boot the OSX discs zen you need to open disk utility (under utilities) then partition it to one and the click options the change it to a GUID partition table Link to comment https://www.insanelymac.com/forum/topic/173288-cant-boot-osx-anymore/#findComment-1194173 Share on other sites More sharing options...
sweetbrett Posted July 18, 2009 Author Share Posted July 18, 2009 that helped, but it didn't really. The install before was on a hdd that was split with windows, so the partition table was already mbr. but i was able to find a new drive to devote to osx all by itself. I was able to install Leo4All v2 but then i followed the Netkas way to update, and as soon as I did the first update to 10.5.3 the install was unbootable again. I know I was able to update following the netkas way before. and i still don't know why my system just happened to become unbootable after a couple months.

sweetbrett Posted August 5, 2009 Author Share Posted August 5, 2009 ok so I've done more testing. I found an old PCI graphics card and took out my new gts250 just to see if it was the vid card causing the problems (since that is the only hardware change I have made since I got osx working the first time). the pci vid card seemed to slow down everything so I could actually read some of the messages that pop up. I tried doing the cd swap method to get retail installed, and once I changed to the retail dvd, I got a bunch of "ebios read error 0x01" which i'm thinking might be the media, but the process gets to a point where it flashes a message saying something like "Detecting CPU Multiplier, if the computer reboots..." but it flashes too quickly to read the entire thing. I've been trying to search for an answer regarding this, but it seems my processor is at fault. Is there any way to remedy this without the purchase of a new processor? like i said, I have a xeon 3050 and it worked perfectly a few months ago. i have no idea why it won't let me boot os x anymore.

sweetbrett Posted August 10, 2009 Author Share Posted August 10, 2009 so i'm guessing there is something wrong with my processor. I can't boot in to any 'distro' using the vanilla kernel anymore. I've reflashed my bios and changed settings but nothing has worked. anyone run in to something like this before?
